Question for anyone who has access to an OAG dated somewhere in the mid-1980s...

In OAGs of the mid-1980s are Swissair's DC-9 and MD-80 equipment types specifically differentiated as D9S, D95 and M80 -- or are DC-9-32, DC-9-51 and MD-81 types all denoted as D9S as in their airline-issued timetables?

...same question for SAS during the same time period as they, like Swissair, categorized their DC-9-21/-41 and MD-81/82 equipment only as D9S in their timetables.
